UNITED STATES PATENT OFFIc GEORGE W. COPE, OF DETROIT, MICHIGAN,ASSIGNOR TO THE ART STOVE OOMPANY,-OF SAME PLACE.

OIL HEATING-STOVE.

SPECIFICATION forming part of Letters Patent No. 504,020, dated August29, 1893.

Application filed December 19, 1892- Serial No. 455,618. (No model.)

To all whom it may concern:

Be it known that I, GEORGE W. COPE, a citizen of the United States,residing at Detroit,

county of Wayne, State of Michigan, have invented a certain new anduseful Improvement in Oil Heating-Stoves; and I declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, which form apart of this specification.

My invention relates to certain new and useful improvements in oilstoves, and more particularly to oil stoves for heating purposes.

The object of my invention is to provide such a stove ofsuperiorutility, simplicity and efficiency.

To these ends my invention consists of the construction, combination andarrangement of devices and appliances hereinafter specified and claimed,and illustrated in the accompanying drawings, in which Figure l, is avertical section of the stove embodying my invention, the section beingtaken on the line 5-8 Fig. 5, through opposite corners to show the finesF. Fig. 2, is a horizontal section on the line 00-00 Fig. 1. Fig. 3, isa horizontal section on the line yy, Fig. 1. Fig. 4, is a detailed viewof the-casting at the base of the inner tube and the drum of the stove.Fig. 5, is a horizontal section on the line zz.

I carry out my invention as follows:

A, represents a leg-frame of the stove.

B, represents the walls of the tank chamber. C, is an oil tank in saidchamber.

D, is a burner, with the wick chamber of which the oil tankcommunicates.

Over the top of the tank chamber is located a cover plate E.

F, is the combustion chamber. At each corner thereof are locatedvertically extended flue tubes F, communicating through the cover plateand through the interior of the tank chamber with the exterior of thestove, at the base thereof.

G, is a plate located at the top of the dues through which said fluescommunicate as shown at g, the plate being also perforated as shown atg, to permit the passage therethrough of the products of combustion fromthe combustion chamber.

F represents mica doors located at the sides of the combustionchamber-between the adjacent lines and cover plate E, and the plate.

G. Above said plate is located a plate or casting H, constructed withchanneled arms H, H H H the arms being preferably arcshaped in verticalcross-section. These arms are made open on the under side so as toreceive the air passing upward through the fines F, and having themarginal edges thereof fitted snugly down upon the perforated arms G ofthe plate G. These several arms, H, H H H communicate at their innerends with a central opening H. A drum I, is mounted upon the plate G,said drum being provided at the top with a perforated plate J,constructed to allow free passage therethrough of the heated air arisingthrough the fiues F, and the combustion chamber.

K, is an interior flue engaging upon the central opening H of thecasting H, the upper plate J, rest-ing thereupon. By this constructionit is evident that the air rising through the lines F, passing throughthe channeled arms of the casting H, and through the inner fiue K,escapes therefrom through perforations in the top plate J. The coverplate E, is constructed with a central opening E the periphery of saidopening setting down snugly upon the collar L, upon the top of theburner.

It will be perceived that by the construction above specified, the airthrough the fines about the combustion chamber and channeled casting orplate H and the inner flue K, has no communication, whatever, with'thecombustion chamber, and consequently is not affected thereby, except asthe air therein is heated by contact with the products of combustionthereabout. It will also be perceived that an air passage M, is formedwithin the tank chamber communicating with the external air at the basethereof. Within the drum I, and exterior to the flue K, is thus formedan air chamber N, communicating with the combustion chamber throughorifices in the plate G, as shown at H. I prefer that the plate G shouldbe made closed or solid at the center and that the perforations IOCtherein, through which the combustion chambercommunieates with thechamber N, should be toward the outer edge of said plate. Thus thecombustion chamber has no communication with the interior of the flue K,the air fines F alone communicating with the inte rior of the flue K,these fines F communicating with the channeled arms H leading into thefine K. The plate H is constructed, preferably, of an integral casting.The plate H is so formed with a common central opening, into which allthe arms lead, said plate having a collar about the upper end of thecentral opening to receive the flue K.

What I claim as my invention is 1. In an oil stove, the combination of abase, an oil burner, a combustion chamber, a plate G located above thecombustion chamber, constructed with perforated arms G, and withperforations g' between said arms, a plate II constructed with channeledarms open on the under side resting upon the arms G of the plate G, andcommunicating therethrough, a drum I, an interior flue K located abovethe plate II and communicating therethrough, and fines F communicatingwith said channeled arms, the chamber between said drum and flue Kcommunicating through the perforations g with the combustion chamber,substantially as described.

2. In an oil stove the combination of a base, an oil burner, acombustion chamber, a perforated plate G above the combustion chamber, aplate H constructed with channeled arms open on the under side restingupon the plate G,a drum I, an interior flue K located above the plate H,and communicating therethrough, and flues F communicating with saidchanneled arms, the chamber between the flue K and the drumcommunieating with the combustion chamber, substantially as described.

3. In an oil stove, having a combustion chamber and an air chamber Nthereabove, a plate G constructed with a series of perforations gthrough which the air chamber com municates with the combustion chamber,and with a series of perforations g at the periphery thereof, a plateI-I constructed with a central opening and with channeled arms restingupon the plate G over the perforations g, an interior flue Kcommunicating with the central opening of the plate H, and verticallyextended air flues located at the corners of the combustion chamber,communicating through the perforations g with the extremities of saidchanneled arms, substantially as described.

l. In an oil stove, the combination of a base, an oil burner formed witha collar L, a cover plate E constructed with a central opening, theperiphery of which rests upon said collar, a combustion chamber, aperforated plate G, a plate H resting upon the plate G, constructed witha central opening and channeled arms, a drum I, an inner flue K locatedupon the central opening of the plate II, and fines F communicatingthrough the plates E and G with the channeled arms of the plate H, theehamberbetween the drum I and flue K communicating through the plateGwith the combustion chamber, substantially as de scribed.

In testimony whereof I sign this speeifieation in the presence of twowitnesses.

GEORGE W. COPE.
